I didn't know there was a novel but that doesn't surprise me as popular light novels getting turned into manhua seems common ... I think even TV shows are turned into graphic novels here in N. Am.
Ch.11 proves again the Pei ZiHeng is just garbage .... Jumps to conclusion/believes Xia Ling to be a murderer based on what? Heresay? Circumstantial as she met for coffee/'chat'? And then turns into a raging hegemon because Xia Ling refuses to remain as 'just' his mistress but he has money, influence, reputation and guardianship (er, she is an adult already) lorded over her, let alone emotionally and physically ....
I need a new male romantic interest to show up soooooon.
